Yep, that's it. Webb is doing exactly what he described "Ah ha! I know exactly what you're trying to do there. You're trying to win a pen but I'm smarter than you. Smarter than all these paying d****eads in the crowd. I'm not giving a pen!" It's the wagging of the finger/crossing of the arms before Suarez has even hit the deck. He decides instantly that Suarez is trying it on and that he's smarter than to let himself be fooled by that.
